Problems solved by technology

[0003] First, the vacuum glass tube is integrated with the heat preservation water tank, which occupies a large space, and the workload of the water heater is also large after entering the water, so there are great limitations in the placement location, resulting in the fact that only residents on the top floor can install it. Using solar water heaters, other users can't install or use them if they want to install them

[0004] Second, due to the limitation of daylighting and bulky installation of desktop solar water heaters, the installation of solar water heaters often affects the beauty and integration of urban buildings. At the same time, the safety brought by the installation of non-top users , water leakage and other social problems have led to restrictions on solar water heaters by local property management departments and relevant government departments

[0005] Third, the heat exchange of water in the vacuum glass tube is a natural exchange in a single body tube. When the temperature is not high, the speed of this heat exchange transfer is ...

Abstract

The invention mainly discloses a non-pressure bearing split type light control solar water heater which mainly comprises a heat collector and a light control integrator. A water tank and the heat collector are arranged in a split manner, and the whole system is controlled by the light control integrator. The water tank is a non-pressure bearing insulation water tank, the heat collector consists of a plurality of vacuum tubes which are transversely arranged, and the position of the heat collector is higher than that of the water tank. The solar water heater is composed of the heat collector, the light control integrator, a light sensor, a main aqueduct and a branch aqueduct, a water returning device, a circulating pump, a solenoid valve, the water tank and the like parts, which can achieve integration of the solar water heater and the building, the independent installation and greatly improved forced circulating heat efficiency; the main aqueduct and the branch aqueduct can cause the heat collector to realize thorough exchange between the cold water and the hot water, the light control integrator can cause the whole system to operate automatically and aperiodically, which greatly improves the work efficiency of the system; the water returning device can cause the hot water in the vacuum tubes to return to the water tank for use, prevent frost crack of the vacuum tubes of the heat collector under the conditions of low light intensity, low temperature or ultra-low temperature, and greatly relieve the thermal efficiency reduction caused by scale deposit generated in the vacuum tubes.

[0021] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings:

[0022] The light-controlled non-pressure-bearing split solar water heater shown in the picture includes a solar heat collector installed outdoors 1, a light-controlled integrator 2, a non-pressure water tank installed indoors 4, and a heat collector 1. It is composed of a plurality of vacuum glass tubes 17 arranged horizontally. The connection of the opposing vacuum tubes 17 is connected by a connector 18. A mother tube 12 is provided in the connector 18, and a branch tube is provided in each vacuum tube 17 13. Above the water tank 4, there is a cold water inlet and a solenoid valve 7, and a water level sensor 8 and a temperature and water level sensor 16 are provided in the water tank 4. The solar water heater passes through the water tank 4, circulating pump 3, solenoid valves 6, 7, and 12 pipes and 13 water pipes. , Light sensor 5, light control integrator 2, etc. form a light control automatic circulation and return system.

[0023] In the above-mentioned solar light-controlled automatic circulation and return system design, the position of the collector 1 must be higher than the position of the water tank 4, so that through the upper and lower shared pipes 10 and solenoid valves 6, the one-way pipe 11 and the check valve 9, the light The control integrator 2 controls the water in the heat collector 1 to return naturally to the water tank 4 through the drop when the light intensity does not reach a certain light intensity.

[0024] In the above-mentioned light-controlled automatic circulation and backflow system design, the light-controlled integrator 2 is detected by the light sensor 5. When the light reaches a certain light intensity, the solenoid valve 7 is opened to enter water. When the water level sensor 8 in the water tank 4 detects water , The light control integrator 2 sends an instruction to start the circulating pump 3 and the solenoid valve 6 at the same time, to send the water in the water tank 4 to the collector 1, and then enter the programming cycle program to circulate by itself, when the light sensor 5 fails to detect a certain light intensity When there is light, the solenoid valve 6 is opened to return the water in the heat collector to the water tank 4 through the drop naturally, and then the solenoid valve 6 is closed to enter the dormant standby state.

[0025] In the above-mentioned light-controlled automatic circulation and reflux system, the entire system will give priority to starting the circulating pump 3 for pressurizing bathing when the bathing switch 14 is turned on under any circumstances. At the same time, the water volume and water temperature in the water tank 4 can be known at any time through the water level temperature sensor 16 and the display 15. In long-term low-light weather conditions, the water can be heated for bathing through the electric heating 19.

[0026] The working principle of the present invention is as follows: when the light sensor 5 detects a certain intensity of light, the light control integrator 2 starts operation by itself, opens the solenoid valve 7 to enter water, and when the water level sensor 8 in the water tank 4 detects water, The solenoid valve 7 is closed, the circulating pump 3 and the solenoid valve 6 are started at the same time, and the water is sent to the bottom of the blind end of the vacuum tube 17 through the pipeline and the mother 12 and branch 13 pipes, the header 18, and the water tank 4 again, and then enters The programming cycle program circulates by itself. When the light sensor 5 does not detect a certain intensity of light, the solenoid valve 6 is opened, the water in the collector 1 is returned to the water tank 4 through the drop, and then the solenoid valve 6 is closed to enter the whole system Sleep standby state. In any case, turn on the bathing switch 14 and the whole system will give priority to start the circulating pump 3 to pressurize bathing.
